The importance of the hairstyles becomes serious to pursuetheir aesthetic interests and the capability of expressing one'sindividual character is judged according to the hairstyle created.Accordingly, it is a well-known fact that women endeavor to expresstheir aesthetic sensibilities with their hairstyles.

A hair curling iron that is one of the beauty tools is divided intoupper and lower portions, in which a curling portion with a semicircularcross-section including a heater means, a heat generating means and acurling tool is provided, respectively. The upper and lower curlingportions are opened centering on a hinge of one side thereof. A heatingpad for generating heat by electricity is mounted in each of the upperand lower curling portions. Moreover, the surface layers of therespective heating pads have various winding shapes such as a roundcross-sectional shape, a triangle cross-sectional shape, etc. so as tocreate various hairstyles by the heat generated while the hair passesthrough the upper and lower curling portions in accordance with thevarious winding shapes. With such a hair curling iron, it is possiblefor women to express their individual characters and aesthetic interestsas described above.

However, such a conventional hair curling iron has a problem in that itrequires a large storage volume and it does not utilize the storagespace efficiently when it is not used, since the upper and lower curlingportions thereof maintain opened centering on the hinge by elastic forceof a spring provided therein at all times.
